Beamstas,
It's not as bad as all that mate. There isn't much that you can't claim if it has a direct connection to the production of assessable income. I've had clients claim part of their Foxtel subscription for news, weather and business channels.
Jonno,
The best thing to do is get a good accountant (read reputable and professional). If you're going to be trading, a good accountant can save you a mint - from tax planning (appropriate corporate structures etc) to advice on what you should be claiming and on and on and on. They're a worthwhile investment.
You can still get a good mid-tier firm to do your return every year and their fees generally aren't a lot more than one of the franchised ones (HR Block etc).
I don't think you'll be able to do anything with the laptop as it's been associated with the tax offset (although i may be wrong). The ipod is a possibility. If you're using it solely for trading then in theory it should be valid (the fact it's got non-trading features is irrelevant; it's the purpose it's put to that matters); dependng on how much it cost, you might have to write it off over a number of years (depreciate it).
Note: the above paragraph is just my feeling on it, and not in any way concrete or advice - I used to be a tax analyst but I'm very rusty.
Cheers,
AMSH.
